Broadband and high-efficiency conversion from guided waves to spoof surface plasmon polaritons
The conversion from spatial propagating waves to surface plasmon polaritons (SPPs) has been well studied, and shown to be very efficient by using gradient-index metasurfaces. However, feedingExpand
Polarization-independent wide-angle triple-band metamaterial absorber.
The triple-band absorber is a promising candidate as absorbing elements in scientific and technical applications because of its multiband absorption, polarization insensitivity, and wide-angle response. Expand
KIR and HLA Loci Are Associated with Hepatocellular Carcinoma Development in Patients with Hepatitis B Virus Infection: A Case-Control Study
Significant associations are identified that suggest an important role for NK cells in HCC incidence in HBV-infected patients, and this study is useful for HCC surveillance and has implications for novel personalized therapy strategy development aiming at HCC prevention inHBV- Infected patients.

Illusion media: Generating virtual objects using realizable metamaterials
We propose a class of optical transformation media, illusion media, which render the enclosed object invisible and generate one or more virtual objects as desired. We apply the proposed media toExpand
Shrinking an arbitrary object as one desires using metamaterials
Based on transformation optics, we present a shrinking device, which can transform an arbitrary object virtually into a small-size object with different material parameters as one desires. Such anExpand

A new method to determine HMM state-number is introduced, based on which an adaptive HMM sketch recognizer is constructed, and a combined feature based on curvature, velocity and geometrical character of stroke for sketch recognition is proposed to improve recognition accuracy. Expand
X-band high directivity lens antenna realized by gradient index metamaterials
This paper presents the theoretical modeling and prototype demonstration of broadband, low loss, and dual polarization capability of a gradient index metamaterial lens using multilayer microstripExpand
Anisotropic coding metamaterials and their powerful manipulation of differently polarized terahertz waves
The ability of the anisotropic coding metasurfaces to generate a beam splitter and realize simultaneous anomalous reflections and polarization conversions, thus providing powerful control of differently polarized electromagnetic waves is demonstrated. Expand
An omnidirectional electromagnetic absorber made of metamaterials
In a recent theoretical work by Narimanov and Kildishev (2009 Appl. Phys. Lett. 95 041106) an optical omnidirectional light absorber based on metamaterials was proposed, in which theoretical analysisExpand
